Question 6: In the coordinate plane $Oxy$, there are two lines:

• $d_1: x + 2y + 3 = 0$
• $d_2: 3x - y + 5 = 0$ and the point $P(-2, 1)$. The line $\Delta$ passes through $P$ and intersects both $d_1$ and $d_2$ at points $A$ and $B$, respectively. The point $P$ is the midpoint of $AB$. The distance from point $M(3, -2)$ to the line $\Delta$ is $\sqrt{5}$. Determine the equation of line $\Delta$.
